Rayleigh-Faber-Krahn, Lyapunov and Hartmann-Wintner inequalities for fractional elliptic problems
Aidyn Kassymov, Michael Ruzhansky, Berikbol T. Torebek
In this paper in the cylindrical domain we consider a fractional elliptic operator with Dirichlet conditions. We prove, that the first eigenvalue of the fractional elliptic operato…
Direct and Inverse problems for time-fractional pseudo-parabolic equations
Michael Ruzhansky, Daurenbek Serikbaev, Niyaz Tokmagambetov +1
The purpose of this paper is to establish the solvability results to direct and inverse problems for time-fractional pseudo-parabolic equations with the self-adjoint operators. We…
Maximum principle for space and time-space fractional partial differential equations
Mokhtar Kirane, Berikbol T. Torebek
In this paper we obtain new estimates of the sequential Caputo fractional derivatives of a function at its extremum points. We derive comparison principles for the linear fractiona…
